The Uni-1.1 API is live today. Built-in prompt enhancement, research, and reference gathering at the API level. Trained in collaboration with Hollywood cinematographers, VFX artists, and world-class artists across cultural forms. Less than half the price and latency of comparable models. Designed for builders shipping in production — and ranked top 3 lab in the Image Arena across Text-to-Image and Image Edit. Start Building → lumalabs.ai/api

Exciting news: UNI-1.1-Max and UNI-1.1 debuts making @LumaLabsAI the #3 lab in the Image Arena across both Text-to-Image and Image Edit! These are versions released without agentic search. Text-to-Image Arena - UNI-1.1-Max #6 overall (1193), +12 points over MAI-Image-2 - UNI-1.1 #7 overall (1190), +13 points over Reve-v1.5 Multi-Image Edit Arena - UNI-1.1-Max #7 overall (1315), +21 points over Seedream 4.5 - UNI-1.1 #8 overall, (1298) Single-Image Edit Arena - UNI-1.1-Max #7 overall (1337) - UNI-1.1 #11 overall, (1310) on par with Grok-Imagine-Image (20260207) Congratulations to @LumaLabsAI on this solid performance!

New viz mode drops. Genuinely the coolest visualization I have seen. We visualize UNI-1's latent embedding space as a 4D hypersphere using SO(4) rotation. You can see how nearest neighbors move together (second half of the video). Implemented by @sane_codes Embedding is using siglip2 by @mtschannen @XiaohuaZhai @giffmana

Most image models are good at one thing. Uni-1 has been good at everything we've thrown at it. Our team generated thousands of images leading up to Uni-1 launch. We embedded them all into a single map where visual similarity determines proximity. The result speaks for itself.

We are loving the energy around Uni-1! Quick note since we’re seeing questions: With Luma Agents, requests can route across models. If you want to make sure you’re using Uni-1, here’s how: - Select Create Image → Uni-1 - Or, explicitly ask the agent to use Uni-1 - Check the model label on outputs to confirm API access coming soon for more direct testing. Keep the feedback coming, and keep on creating → lumalabs.ai/uni-1.

A fixed text token length is a limitation of most existing text-to-image models. In Uni-1, we engineered around this, so that it can take at least 3500 tokens (even in markdown) if you want to promptmaxx. The differences is huge between Uni-1 (1st image) and Flux 2 (2nd image).

Uni-1 is here! A new kind of model that thinks and generates pixels simultaneously. Less artificial. More intelligent.

UNI-1 is intelligent, directable, cultured. Incredible range it can do. Incredibly proud of the world-class team building a world-class model. It’s a daunting task to go up against industry giants like Deepmind/OpenAI/Bytedance. More to come! API, technical report, model card… Come join us!

Excited to introduce Uni-1, our new multimodal model that *unifies* understanding and generation. TLDR: a team of ~15 researchers is going pound-for-pound with nano banana and gpt image 🧵

Excited to introduce Uni-1, our new *unified* multimodal model that does both understanding and generation: lumalabs.ai/uni-1 TLDR: I think Uni-1 @LumaLabsAI is > GPT Image 1.5 in many cases, and toe-to-toe with Nano Banana Pro/2. (showcase below)

Discrete or continuous tokens? Or even tokenizer-free? The visual modeling debate rages on, but for now, let me introduce L24SQ, a provably optimal, regularizer-free quantizer with a large codebook (~200k), achieving SoTA reconstruction-compression tradeoff and generative power!
